Showers account for 18 percent of residential indoor water use. When you consider that the United States uses nearly 1.2 trillion gallons of water a year just for showering, it is easy to see why low-flow showerheads can have a big impact on water consumption and efforts to conserve water at home. (To put this figure in perspective, 1.2 trillion gallons is enough water to supply the water needs of New York and New Jersey for an entire year!)By simply switching to a low-flow showerhead, everyone can participate in water and energy conservation. +

A set of Sharing Cities principles — with no claim of comprehensiveness — that people could apply, adapt, and add to, according to their local circumstances. The principles should be thought of as aspirations rather than instructions; guiding stars rather than a map. Here are the principles (with detailed descriptions below), written with the help of Shareable staff and our community, with inspiration from many others in the movement and beyond. +
This page will cover basic 12 lead interpretation acceptable for most field paramedics. Remember that this is an incredibly in depth topic, and can easily be overwhelming. With that in mind, this page will not cover more complex electrocardiographically significant findings such as, but not limited to: atrial enlargement, fascicular blocks, q-wave infarction/NSTEMI, Brugada's syndrome, Sgarbossa's Criterion, etc. All information on this page is introductory in nature and can be expanded upon; it is recommended that you perform self-study constantly even after receiving your paramedic license. This page will not cover rhythm analysis as that has been covered in the EKG Rhythm Interpretation page of this course. If you have questions regarding placement of the EKG electrodes or on the basic reasoning surrounding the production of the waveform, look to the linked portion of the Setup for ALS page from the EMT section of Appropedia. If you need a refresh on the basics of cardiac anatomy and physiology, navigate to the Physiology of the Heart page. +
This quiz is designed to test your knowledge of basic 12 lead EKG analysis. Read each question fully and make sure you understand what the question is asking before you answer. Some questions are select all that apply, these will be marked by square check boxes. After answering all questions to the best of your ability, click the “Submit” button at the bottom of the page. Your score will be shown at the bottom of the page after submission. You may reset this quiz as many times as you would like.

Unlike 4-stroke diesel engines, 2-stroke diesel engines use a 2-stroke Diesel cycle, and are much more energy efficient (50% efficient as opposed to 35% of 4-stroke Diesel engines). The 2-stroke Diesel engine cycle differs significanly from 2-stroke gasoline engines as they do not mix lubricants with the fuel. They hence avoid all of the extra pollution (compared to 4-stroke engines) that normally occurs in the case with gasoline engines. This, unlike gasoline 2-stroke engines, makes them a appropriate technology 2-stroke engines. +

The 2009 Victorian bushfires on Saturday 7 February 2009 were the worst bushfires in Australia's history, surpassing both the Ash Wednesday fires in 1983 and the Black Friday fires in 1939. +
The 2010 Xinfa aluminum plant protest (信发铝厂污染引抗议) occurred when the Chipping County, Shandong Xinfa aluminum & power group (山东信发铝电集团) began when villagers started complaining about pollution created by the factory. A protest broke out in one of the villages in Guangxi, People's Republic of China. +
Team ATLAS, a group of Spring 2022 Environmental Resources Engineering students at Cal Poly Humboldt, designed and built a photovoltaic system that recharges a power bank that charges laptop and smartphone devices. This project was intended to provide information to build a mid-quality mid-cost product that not only competes with the power bank market today but also has the ability to replace components, utilize renewable energy, and customize the product to the user's desire. +
This is a landing page for the partnership between Cal Poly Humboldt's Engineering 215 course and The Appropedia Foundation. This deeper partnership started in the Spring Semester of 2022 as a way to accelerate access to open access, DIY, projects that are easy to replicate and meet local needs. +
Cassiopeia is a portable and durable computer capable of operating completely off solar power and without access to the Internet. The design consists of a Raspberry Pi 3b+, 9W fold-able solar panel, lithium-ion rechargeable battery, and container to house it all. The project was designed and built in the spring 2022 semester by Cal Poly Humboldt students enrolled in Engineering 215: Introduction to Design. The team, Suns of Community, consisted of Zane Cook, Max Cunningham, and Phil Tran. +
The Solar DIY Air Filter designed by Radiant Enterprises is a project aimed at creating a design for an accessible, replicable air filter design that can be used in power-outage instances, and was designed during the Spring semester of 2022 at Cal Poly Humboldt. The motivation for this project was to create a design that would both be useful in emergency situations and impactful on a larger scale. The full technical design document can be found here. +
The Emergency Photovoltaic Box, created for Appropedia, provides an affordable source of clean power during shelter-in-place emergencies where power is often lost. The project includes a collection of emergency preparedness resources as well. This project was designed and created by Elemental Solar, a team of students; Emily Handy, Justin Romani, and Sol Wright. These are students from the California Polytechnic University, Humboldt Spring 2022 section of the Engr205 Introduction to Design course. +
The Mahana PV Window Fan is a solar ventilation system intended to provide air conditioning to those without reliable access to electricity in high heat regions. The project was designed and built by student group Solinary, comprised of Lily Cohen, Lucille Larson, and Hope Sakho, in association with California Polytechnic University at Humboldt as part of the course Engineering 215 - Introduction to Design. The paramount goal of this project is to remain accessible, universal, and replicable in design while providing an effective alternative to plug-in window fans. +
Designed and constructed in Spring of 2022, the low-power/high-value PV system was built to provide power to low-end medical equipment such as glucometers and Continuous Positive Airway Pressure (CPAPs) in the event of a power outage or "brown out." +
The RepRap motto is "wealth without money" - for this assignment you are to create wealth by making an open source design that has value to you. It must be 3D printable on your Jellybox and cost less than a commercial equivalent (if such a thing exists). +
